Assembly locking device, a connecting bolt in combination with the assembly locking device, a component with a pre-installed connecting bolt by means of the assembly locking device as well as a manufacturing method for the assembly locking device and an assembly method of a connecting bolt with the assembly locking device within a component opening

An assembly locking device adapted to a shaft of a connecting bolt with a bolt head so that the assembly locking device is positionable on the shaft in a loss-proof manner and the connecting bolt is arrangeable in a pull-out-proof manner inserted into a component opening with the help of the assembly locking device, wherein the assembly locking device includes the following features:

• a. a wire coil comprised of a plurality of helically wound turns, the wire coil having a first end and a second end,
• b. starting at the first end of the wire coil, a holding turn is provided which extends over an angular range of at least 360° about a central longitudinal axis of the wire coil and comprises an inner diameter DH,
• c. following the holding turn, a clamping coil portion is arranged that is formed like a truncated cone having a plurality of subsequent turns of an increasing inner diameter DK compared with the holding turn, with the clamping coil portion extending over at least two turns about the central longitudinal axis of the wire coil and comprises a pitch PW that is larger compared with the holding turn, and
• d. following the clamping coil portion and at the second end of the wire coil, a positioning turn is provided,
• d1. extending over an angular range of at least 270° about the central longitudinal axis of the wire coil,
• d2. having an inner diameter DP for which DK>DP≥DH applies, and
• d3. having a smaller or no pitch PP compared with the clamping coil portion, so that
• d4. an end of the shaft, facing away from the head, of the connecting bolt is receivable in the positioning turn and the connecting bolt is holdable aligned in the component opening in a clamping manner by means of the holding turn and the positioning turn.
